WATER-CLOSET BLEND.

Application filed June 29, 1925. Serial No. 10.416,

This invention relates to plumbing fixtures the connection of the closetwith the soil pipe andwhich carries the soil from the closet to thestack and so constructed as to provide for the discharge of the wastefrom the bathtub, lavatory or other fixtures into thebend. The object ofthe inventionfis to provide a bend of wrought iron construction for,threaded engagement with the various pipejconnections which are usuallyof cast eliminated.

iron. r I r I V 7 In the presenttype of building construction the use ofthe old type of cast iron closet bends adapted to be caulked to thepiping are inadequate for thepurpose due to the fact of their beingreadily broken but which, with a wrought iron connection, is largelyeliminated. the invention is in the provision of a closet bend ofwrought iron-construction that is simple in form adapted for threadedconnecprovided with a hub for connection ofa waste piping bend above thelevel of the water that may flow through the bend thus opening thepocket to the stack above the a level ofthe water in the bend and thusventmg ofwhat may betermed a pocket with which the waste line isconnected. In this present construction I have provided a pocketofsomewhat different character Which is not vented through the bend but isdirectly vented by a vent line to atmosphere or to the'stack, theconstruction providing a pocket above the possible level of the flowoffrom lavatories, smks etc., a'ndas provided the fluid through the bendwhich pocket is not vented to the discharge stack through the bend;These objects and the several novel features of the invention arehereinafter more fully described and claimed, and

the preferred form of construction of a closet bend embodying myinvention isshown in theaccornpanying drawings in which- Fig. -1 is aside view of my improved bend. Fig. 2 is an end view thereo I r Fig. 3is a longitudinal sectionfshowing A particular feature of clearly theimproved arrangement otthe waste piping pocket for the connection oi orthe likee with the bend.

As previously stated, thebend hereshown' and described is formedofwroughtironfor screw-thrcaded connectionw th the piping or fixtures tobe connected therewith Th1s,-as

is shown clearly inthe drawing, o'l the usual general form of the bendhaving the threaded end 1 to receive the fittingwith which the closetmay be connected to the bend (not here shown) and at the opposite end isprovided wit'hthe threaded hu'b 2 wrhich is connected with the stack bya short piping. 7 On the surface of the bend 1 pro vided what I havetermed a pocket 3 which is above the general level of-flow oit' fluidthrough the bend as will be understood'from h1g3. This pocket. asstated, formed on. the upper side of the bend and on the interior oi thebend 21 depending lip 4 is vprovided at the forward end of the pocketwhich in reality determines the eifect'of the bore of the bend for thepassage of the fluid. At the rear end the pocket also has a seconddepending flange 5 which terminates above the flange 4t and provides aventing of the pocket to the discharge piping with which so i the bendis connected through the bend itself. The purpose of venting the pocketto atmosphere as has been previously'stated, is l f to prevent asiphonage of the conduits connected with the pocket and the structuresherein used for the purpose, although'the connection of the piping tothe bend may be above the general 'level of flow of liquid therein, yetupon discharge of the closet this area at the rear of the bend doesnotalways provide a proper vent space particularly where several suchcloset bends are con nected with a single stack and flushedsimultaneously; This pocket is provided with threaded hubs on oppositesides indicated at 6 and 7, for the connection of wa-ste'piping on theupper surface with a threaded hub 8 to which the-vent pipe may beconnected.

bility of closing the pocket to atmosphere and thereby siphoning thewaste connections to the pocket as has beenposs ble with such structuresin which the pocket was vented through the bend to the stack, By thisgeneral arrangement described a movable fitting is provided forconnecting the closet, water conduits, and vent at one point in thedrainage system of the modern type in which the fittings and pipeconnections are screwthreaded.

From the foregoing description it becomes evident that the device isvery simple and efiicient in operation, will not easily get out oforder, is of comparatively low manufacturing cost, and provides a devicewhich accomplishes the objects described.

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1, A water closet bend having threaded inlet and outletends, said bend being constructed with a pocket in the upper surfacebetween the said ends, the wall defining the pocketat the forward endextending below the wall defining the pocket at the rear end, the saidpockethaving hubs for the connection of waste piping, and a ventconnection in the upper side thereof.

2. In a. water closet bend having an inlet end for the connection with acloset fixture and an outlet end for connection with a waste conduit anda pocket in the uppersurface thereof above the outlet end of the bendthe forward wall of the pocket extending nearer the longitudinal axis ofthe bend than the rear wall of the pocket, an inlet in communicationwith the said pocket and a connection for a vent in the upper part ofthe pocket,

3. A water closet bend having an inlet end, the axis of which is in avertical plane and adapted for connection with a closet bend, and anoutlet end, the axis of which is in a horizontal plane adapted forconnection of a conduit therewithin, a pocketforn'ied in the uppersurface of the bend above the bore and extending from the side of theinlet end to adjacent the outlet end, the'rear wall of the pocketextending into the bore and the forward wall of the pocket extending toa plane below the plane at which the rear wall terminates andrestricting the flow through the inlet to a volume less than thatpermitted by the terminal per tion of the rear wall, said pocket havinghubs in the side thereof for a waste pipe connection and an opening fora vent connection 1n the upper surface. 7

In testimony whereof, I sign this specification. v
